Hanoi street Food Drink -- Walking street food drink tours - Hanoi Street Food
The cuisine in the north is different to that of the south. Southerners would claim that northern food is bland whereas the citizens of the north would argue that it’s simpler and elegant thus requiring less use of spices and sweetness, allowing the ingredients to speak for themselves. For a visitor on a flying visit, deciding on where to eat can be daunting at the best of times. Trip Advisor is usually the first port of call, but inconsistent reviews can cast a cloud of doubt over the legitimacy of the medium. Here is a list of my favourite dishes and venues for eating and drinking in Hanoi if you were here for a short weekend of culinary indulgence. Start training and make some room. You will need it by the end of a weekend here.

Bun cha Hanoi- Hanoi Street Food
Possibly the most delicious food available to man, bun cha is the lunch of choice all over Hanoi.

Pork patties and slices of pork belly are grilled over hot coals and served with fish sauce, tangy vinegar, sugar and lime, which, when combined, creates a sort of barbecue soup that is eaten with rice vermicelli and fresh herbs.

Accompanied by deep-fried spring rolls, this calorically rich dish is served with garlic and chilies on the side for an extra kick.

Pho - Hanoi Street Food 
As the birthplace of pho, Hanoi is ground zero for the fragrant rice noodle soup served with fresh herbs that has become popular all over the world. It's no surprise, then, that Hanoi's pho is outstanding. Two variations are most popular: pho ga (with chicken) and pho bo (with beef). Pho is traditionally served as a breakfast food, so you'll find pho sellers all over town from before dawn to mid-morning.

Try it at: Pho 112, 112 Van Phuc, Ba Dinh, Hanoi

Barbecue chicken - Hanoi Street Food

Ly Van Phuc is its official name, but the place is colloquially known as "Chicken Street" in honor of the tasty poultry being barbecued up and down this crowded alley.

Grilled chicken wings and feet, sweet potatoes and bread that's been brushed with honey before being grilled are served with chili sauce and pickled cucumbers in sweet vinegar.

The simple, enticing menu is nearly identical for all the vendors on the street.

Xoi - Sticky rice - Hanoi Street Food

In the morning you'll find the sticky rice vendors out hawking their wares. Sticky rice is a hugely popular carb-rich breakfast food that comes wrapped in a banana leaf. There are dozens of variations on the dish.

One is served with crushed peanuts and sesame salt, another involves white corn and deep-fried shallots.

Iced coffee - Hanoi Street Food

Coffee was brought to Vietnam by the French and is, along with baguettes, one of their lasting culinary legacies. Beans are grown in Vietnam and roasted, often with lard, before being ground and served in single-serving metal filters.

Drinking a cup of cafe nau da, iced coffee with condensed milk, on a busy side street is one of Hanoi's great pleasures.

You can find many types of excellent spring rolls all over Vietnam, but nem cua be, made with fresh crab meat, are particularly good. Unlike regular spring rolls, they are wrapped into a square shape before being fried.

Nem cua be are a specialty of Hai Phong, a seaside town not far away, but are fantastic in Hanoi as well.

Toast has nothing on chao ca, so if you're looking for a satisfying breakfast in Hanoi, why not try a steaming bowl of fish porridge?

Like Chinese congee, it's a rice gruel made by cooking down the grains until they are nearly liquid. In Hanoi, it's most often served with green onion, sprigs of dill and slivers of ginger.

Try it at: Doan Xom Chao Ca, 213 Hang Bang, Hanoi

Banh cuon is a Northern Vietnamese dish that migrated to Hanoi. Thin steamed rice flour pancakes filled with minced pork and cloud ear mushrooms are served with nuoc cham, a fish-sauce-based dipping sauce, fried shallots and fresh herbs. Slightly goopy in texture, banh cuon are often eaten for breakfast or as an evening pick-me-up.

There's no greater pleasure than drinking on a busy Hanoi sidewalk, and what better to nosh on at while you do than muc nuong? Dried squid is grilled over hot coals before being shredded and served with a spicy sauce. It's a chewy treat that is best washed down with shots of rice wine.
